CN2181680Y - Counter-weight-free balance - Google Patents

Abstract

The utility model provides a counterweight-free balance, which is a platform balance or wagon balance. The counterweight-free balance comprises a balance seat, a rack which is fixed at one end of the balance seat and is provided with a bearing bar, a top knife, a bar stabilizing strip and a bar pressing block which are fixed at the other end of the balance seat, and a frame type balance bar which is connected with the balance seat and is composed of two parallel balance bar strips, wherein, at least one sliding counterweight is arranged on each balance bar strip. The utility model has the advantages of large weighing range and accurate weighing. Each weighing unit can be read out from each balance bar strip. Because the counterweight-free balance has no separated counterweight, the use is convenient, and the loss or the exchange of the counterweight is avoided.

Description

Counter-weight-free balance

The utility model relates to a kind of metering outfit, particularly relates to a kind of balance without weight.

It is desk-top and portable to use the scale of being with the separation sliding weight of steelyard to have at present, because scale separates with stone roller, can occur sliding weight of steelyard during use and lose, or the inaccurate sliding weight of steelyard of operating weight, cause the weighing result error big, use, carry inconvenience.

The purpose of this utility model is to provide a kind of and has only the slip on the arm beam of steelyard to claim sign indicating number, and does not use the balance without weight that separates sliding weight of steelyard.

The utility model balance without weight is to realize like this, it comprises scale base, pass through web member, be connected the arm beam of steelyard on the scale base as screw rod, be fixed on the support and the top cutter of scale base one end band load bar, on the load bar scale pan frame can be set, be used for load-bearing by the weighing object, the top cutter is used to support the arm beam of steelyard one end, and is fixed on rotating depression bar piece and the steady bar strip that supports the arm beam of steelyard other end on the scale base other end.To be pressed in steady bar strip under the arm beam of steelyard when depression bar piece is used for not weighing, avoid arm beam of steelyard swing.Wherein the arm beam of steelyard is the frame-type that is made of at least two parallel arm beam of steelyard bars, generally be advisable with 2～5, scale is arranged on the every arm beam of steelyard bar and slide and claim sign indicating number, slide and claim sign indicating number to be generally 1-3, title code weight amount difference on the different arm beam of steelyard bars, increase progressively from top to bottom, so that accurately weighing is to certain degree of accuracy, the slip on the same arm beam of steelyard bar claims that the code weight amount is identical.

The utility model balance without weight can be designed as desk-top or the weighbridge formula, and principle does not just have the sliding weight of steelyard that separates, and claims sign indicating number to replace with more slip with general platform balance.Moving right successively from top to bottom during weighing slide to claim sign indicating number, claims sign indicating number to move to right-hand member still can not weighing the time as the slip on the uppermost arm beam of steelyard bar, and the slip that can move successively on the following arm beam of steelyard bar claims sign indicating number.When the arm beam of steelyard was in the equilibrium position, the reading summation on each arm beam of steelyard bar was the weight of weighed object.

The advantage of the utility model balance without weight is not use the separation sliding weight of steelyard, has avoided the sliding weight of steelyard loss, has also avoided sliding weight of steelyard to open hat Lee generation, practises fraud, and guarantee the accuracy of weighing, and range of weighing is big, and is easy to use.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 2: the A among Fig. 1 is to view

Fig. 3: the B among Fig. 1 is to view

The utility model balance without weight comprises scale base 1, be connected with scale base 1 and be with by screw rod 2 and slide to claim sign indicating number 3, the frame-type arm beam of steelyard 5 that constitutes by three parallel arm beam of steelyard bars 4, one end of scale base 1 is fixed with the support 7 and the top cutter 8 of band load bar 6, and the other end of scale base 1 is fixed with rotating depression bar piece 9 and steady bar strip 10.

Claims (1)

1, a kind of balance without weight, comprise scale base, the arm beam of steelyard that is connected and is with the title sign indicating number that slides with scale base, be fixed on the support and the top cutter of scale base one end band load bar, and be fixed on steady bar strip and depression bar piece on the scale base other end, it is characterized in that the arm beam of steelyard is the frame-type that is made of at least two parallel arm beam of steelyard bars, have the title sign indicating number that slides on the every arm beam of steelyard bar at least.
